I'll be very brief.
There are no guarantees in the world of disability in terms of getting it right the first time. You sometimes do make mistakes, and you have to move on and adapt.
Universal design is really where it's at. And we have to understand that when you do make changes like curb cuts and so on, it will create challenges for people with visual impairments or low vision. But at the same time, it's universal insofar as it helps people with strollers, carriages, if they're carrying luggage and rolling it along, whatever the case may be. So I think universal design is really the way we need to go in the future. You do it in the preparation stage and not as an afterthought. Then you have to adapt it at times after that in order to make it work for situations that aren't always contemplated. But universal design is clearly something this committee should be thinking about.
